FLOORING-CLAMP.

SPECIFICATION forming part of Letters Patent No. 654,365, dated July 24,1900.

Application filed July 29, 1899. Serial No. 725,513. (No model.)

To all whom, it may concern:

Be it known that we, ARTHUR LUOIUS SToWELL and ARTHUR HERMAN RoUNDs, ofGays Mills, in the county of Crawford and State of Wisconsin, haveinvented a new and Improved Flooring-Clamp, of which the following is afull, clear, and exact description.

One object of our invention is to provide a simple, durable, andeconomic device for clamping flooring together when laying the same andfor drawing down drop-siding, ship-lapped sealing, or any matched or unmatched lumber where it is necessary that a tight joint should be made,and whereby She material may be laid upon joists or studing.

Another object of the invention is to construct a flooring-clamp capableof use upon lumber of different thickness and which may be manipulatedwith one hand.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the improved device, parts thereof beingbroken away. Fig. 2 is a perspective view of the device, illustrating itas applied to studding and sealing to be secured to the studding. Fig. 3is a section taken practically on the line 3 3 of Fig. 1, and Fig. l isa section taken substantially on the line 4 4 of Fig. 1, but looking inan opposite direction.

A plate A is employed adapted to engage with the edges of the boards 0,that are to be secured either to studding D, as shown in Fig. 2, joists,or their equivalents. This plate A may be of any desired size and isprovided near one end upon its upper face with a bear ing 10 of anysuitable character, and near its opposite end, also uponits upper face,the said plateis provided with transversely-alluing jaws 11.

A body-arm B is used in connection with the plate. This arm comprises asleeve 12,

having a horizontal recess 12 in its outer end, a member 13, and aconnecting member 14, the connecting member being at an angle to boththe sleeve 12 and themember 13. The member 13, which may be termed thebiting member, is provided with a polygonal or square section 15. Thissection is located between the jaws 11, and one face of the sectionrests upon the upper surface of the plate. The'jaws 11 firmly clamp thebiting member 13 adjacent'to each end of the polygonal section 15, andat the outer end of the biting me1nber l3 a spur-l6 is secured orintegrally formed, and this spur is curved inwardly and upwardly andextends upward at an angle to the upper face of the plate A When thedevice is horizontally located. Thus it will be observed that thebody-arm B is rigidly attached to the plate A.

A clampingbar 17 is mounted to turn loosely in the bearing 10, and saidbar 17 is carried loosely through the sleeve 12 of the body-arm and isattached to a handle 18. A lug 17 is formed upon said clamping-bar, andthis lug is adapted to turn in the recess 12 of the sleeve of thebody-arm B, as shown in Figs. 1 and 4.. A dog 19 is located at the outerend of the clamping-bar 17, opposite the spur 16, and said dog isprovided with an inner convexed surface and usually with an outerconcaved surface. The dog is further provided in its inner convexedsurface with series of teeth 20, as shownin Figs. 2 and 3.

It will be observed that the bearings 10 and 11 are made in twosections, so that the parts to be received may be placed between thesections and the sections shaped over the parts.

In operation when the device is to be used in connection with studding Dthe plate A is made to rest upon the upper edge of the board 0 to belaid, or that edge of the board which is to receive a fellow board, andthe spur 16 is made to enter one side of the stud= ding. Theclamping-bar 17 is then turned to bring the teeth of the dog 19 inengagement with the opposite side of the studding, and by furtherturning the bar 17 upon the dog 19 as a pivot-point the board Owill beforced against the board previously laid and. may be held in closeengagement with saidboard until the board to which the device is appliedcan be nailed properly to the studding.

The device is exceedingly simple, durable,

and economic, and, as stated, may be readily manipulated by one hand.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent-- l. A clamp, comprising a compressingplate, anangular armattached to said compressing-plate, one member of whichangular arm is tubular, a spur attached to one member of said angulararm, a bar held to turn in the tubular portion of the angular arm, and adog carried by said bar, the dog being opposite said spur and providedwith teeth in the surface that faces the said spur, for the purposedescribed.

2. A compressing-plate, an angular bodyarm secured rigidly to saidcompressing-plate, the inner member of said angular body-arm beingtubular and the outer member provided with an inwardly and upwardlycurved spur, a bar held to turn upon the co mpressing-plate and in thetubular portion of the body-arm, and a curved dog secured to the outerend of the said bar, the convexed face of which dog faces said spur andis toothed, for the purpose described.

3. A compressing-plate, an angular bodyarrn secured rigidly to saidcompressing-plate, the inner member of said angular body-arm beingtubular and the outer member provided with an inwardly and upwardlycurved spur, a bar held to turn upon the compressing-plate and in thetubular portion of the body-arm, a curved dog secured to the outer endof the said bar, the convexed face of which dog faces said spur, ahandle for the said bar, and means for limiting the movement of the saidbar, for the purpose set forth.

4:. In a flooring-clamp, a compressing member, a stationary clampingmember comprising an arm extending at right angles beyond one side ofthe compressing member, terminating in a spur, an intermediate sectionex tending along the opposite side of the compressing member and asleeve at an angle to the intermediate section, a bar held to turn inthe sleeve-section of the clamping member, and a dog fastened to saidbar, the working surface whereof faces the spur, as described.
